Interesting, seems like quite a bit of work is needed to do this in rust, but hopefully that will benefit others who need to do the same. I do wonder if all of the efforts to do it in rust will be worth it though.
Dunno. All I know is it’s tied to supporting reclocking on newer Nvidia GPUs. This is something the Nouveau kernel driver already supports, so I guess this is just rewriting in Rust for the sake of rewriting in Rust.
It’s an NVIDIA specific term that is the abbreviation for GPU System Processor. It’s a RISC-V core that does all sorts of management tasks on a modern Nvidia card, mostly related to task setup, resource allocation, context switching, adjusting clock speeds, etc.
